VV series 500 powders in 300Win Mag

[wboggs]

I'm looking for help in selecting the best powder for bullets in the 200-230 weight range loaded long to about 3.51 in a .300 WM.
Would appreciate your comments, especially for the VV series 500.
Thanks

I use N560 with 200gr Bergers in mine, N560/N565 should give you the best speed until you get to 215gr + weights. For the real heavies look at N570

When I was testing the Navy loads, I was using VVN-565 under the 220 gr. Sierra MK for my best results.

Worked up load in 300 prc for a friend used N570 and 215 Berger. Went up to 3050 fps before showing case head expansion but went with low node of 2925 fps where it shoots best. He killed a 5x5 bull first morning out went 5’ and dropped. Yours should work about same. I also use N570 in 28 Nosler 195s and 25-06 Ackley 133s.

Did you try any N560, N565, or H1000?
I agree with load below max pressures. No reason to live on the ragged edge.
Thanks for your comments.

No just N570. It was so good I saw no reason to try anything different. My loads are all below max. Another 300 prc I did H1000 and 215s and shot very well best load was 20fps less than 570 in other rifle

I have lots of H1000 and no N500 series
Whan I need a new supply, I will start with N570 if there is a reliable supply.
I note the same company ownes. Berger, Lapua, and VV.
Thanks

When n570 works it works well
My 338 loves it.
N565 in another good option being similar to R26.

N565 is getting hard to find. Do you think VV will continue to supply powders in rhe future?

 

[L.Sherm]

I couldn't get enough V565 or H1000 in a 300WM case to get the speed or accuracy that I got with RL23 using a 185 Berger.

 

[SeabeeKen]

565, 568, 570 will work fine. VV has no intention to stop supplying powders to reloaders, as per a previous comment from them. Keep in mind that the 500 series of powders are double based and 565 and 570 have an explosive heat index of 4000 degrees.

My go-to hunting load is a 210 VLDH Berger with 76.6gn of H1000 set 18thou off the lands. Groups consistent sub .250 five shot groups out of my RBros built Remington 700 with a Proof Carbon Barrel. Cases are fire formed and bumped .004. I like a little more bump on a hunting rifle as the potential for debris in the field is a larger concern than when target shooting.

Pretty big jump for a VLD but there is no question about your load.
What brass do you use?
